Dr. Sarwat Salim presents a case of advanced low-tension glaucoma to highlight the appropriate use of ancillary testing to monitor progression and guide therapeutic intervention. In advanced glaucoma, structural evaluation with OCT is often limited and functional evaluation with perimetry can be more useful.

Dr. Robert Weinreb discusses the advantages of various approaches for detecting glaucoma progression. To come up with the best approach for each patient, physicians should take into account both visual field tests and structural tests.

Dr. Mildred Olivier discusses a case of a 58-year-old white man who presented to his primary ophthalmologist with intermittent blurred vision and increased pressure. Visual fields and posterior pole evaluation along with the pallor were not consistent with the clinical picture.

Dr. Kouros Nouri-Mahdavi reviews the benefits and limitations of various perimetric tests and strategies, spot sizes, and guided progression analysis software. His presentation covers the definition of advanced glaucoma, the issues with standard achromatic perimetry size III, which type of perimetry to use, what tests to perform, and issues with available tools.

Dr. Angelo Tanna reviews the evidence and offers advice on the best strategies for the early detection of glaucoma. He discusses techniques such as imaging of the optic disc, peripapillary retinal nerve fiber layer, and the macula, wide-field OCT scanning, and assessment of the Bruch's membrane opening minimum rim width.

Visual field testing is critical for assessment and to document progression of glaucoma, but is inherently prone to errors and artifacts. Common causes for artifacts include patient-related factors; eye-related factors; central nervous system defects; and optic disc, optic nerve, and chorioretinal disorders.

This lecture from AGS 2018 a panel discusses how best to handle the case of a 86-year-old patient in good health with elevated eye pressure, small cup-to-disc ratios, progressive "green disease" in both eyes, and full visual fields.

This lecture from AGS 2018 a panel discusses how best to handle the case of a 73-year-old patient with open-angle glaucoma that is fairly stable, his pressure has been reduced with medication 20%-25% from baseline, a reliable visual field taker, and OCT scans show thinning in each eye.

This lecture from AGS 2018 reviews findings from the Tube Versus Trabeculectomy (TVT) and Primary Tube Versus Trabeculectomy (PTVT) studies and provides some guidance in using the data and its application in clinical practice, with emphasis on intervention at different stages of the disease, from early to advanced glaucoma.
